Researchers have found a new way to optimize nickel by unlocking properties that could enable numerous applications, from biosensors to quantum computing.

Easy-to-use technique to measure the hydrophobicity of micro- and nanoparticle

The technique may have a far-reaching implication for many scientific and industrial applications and disciplines that involve particulate matter.

Blanket of light may give better quantum computers

Researchers describe how -- by simple means -- they have created a 'carpet' of thousands of quantum-mechanically entangled light pulses. The discovery has the potential to pave the way for more powerful quantum computers.

Weaving quantum processors out of laser light

Researchers open a new avenue to quantum computing with a breakthrough experiment: a large-scale quantum processor made entirely of light.

Double layer of graphene helps to control spin currents

In order to make transistors that operate using the spin of electrons, rather than their charge, it is necessary to find a way of switching spin currents on and off. Furthermore, the lifetime of the spins should at least be equal to the time taken for these electrons to travel through a circuit. Scientists have now taken an important step forward by creating a device that meets both of these requirements.

Physicists develop fast and sensitive mechanical tool to measure light

Physicists have developed a fast and sensitive mechanical tool to measure light. The graphene nanomechanical bolometer is the fastest and most sensitive in its class. It is poised to detect nearly every color of light at high speeds and obtain measurements at and far above room-temperature.

Reducing open-circuit voltage loss in organic solar cells

Researchers at Institute for Molecular Science in Japan report that organic solar cells (OSCs) with high mobility and highly crystalline donor (D) and acceptor (A) materials were able to reduce an open-circuit voltage (VOC) loss. The origin of the high VOC was that the highly crystalline D/A interface reduced the energy loss related to charge recombination. The results demonstrate that careful design of the D/A interface enables high power conversion efficiencies in OSCs.

Ultrafast particle interactions could make quantum information devices feasible

Energy is information. Lengthening the time during which a system is capable of retaining energy before losing it to the local environment is a key goal for the development of quantum information. This interval is called the "coherence time." Several studies have been performed with the aim of retarding decoherence.

Bio-circuitry mimics synapses and neurons in a step toward sensory computing

Researchers at the Department of Energy's Oak Ridge National Laboratory, the University of Tennessee and Texas A&M University demonstrated bio-inspired devices that accelerate routes to neuromorphic, or brain-like, computing.

Creating and trapping trions at room temperature

A team chemically engineered carbon nanotubes to synthesize and trap trions at room temperature. Trions are quasi particles that can potentially carry more information than electrons in applications from bioimaging to chemical sensing and quantum computing. The research makes it possible to manipulate trions and study their fundamental properties in ways that have never been possible before.
